TLC of alkaloids on cyanopropyl bonded stationary phases. Part II. Connection with RP18 and silica plates.
Ní féidir ach le húsáideoirí cláraithe ailt a aistriú
Logáil Isteach / Cláraigh
Some standards of the alkaloids and synthetic or natural mixtures are separated by two-dimensional thin-layer chromatography (TLC) on different adsorbent layers. Normal- and reversed-phase systems are used to obtain significant differences in the separation selectivity. Optimization of the
Thin-layer chromatography of alkaloids on cyanopropyl bonded stationary phases. Part I.
Ní féidir ach le húsáideoirí cláraithe ailt a aistriú
Logáil Isteach / Cláraigh
Selected alkaloids are chromatographed on cyanopropyl-silica thin layers using various nonaqueous and aqueous eluents. Because of the strong retention of these basic compounds, nonaqueous eluents containing medium polar diluents, strongly polar modifiers, and silanol blockers (ammonia or
Effect of chromatographic conditions on the separation and system efficiency for HPLC of selected alkaloids on different stationary phases.
Ní féidir ach le húsáideoirí cláraithe ailt a aistriú
Logáil Isteach / Cláraigh
Retention parameters of alkaloid standards were determined on different stationary phases, i.e., octadecyl silica, base-deactivated octadecyl silica, cyanopropyl silica, preconditioned cyanopropyl silica, and pentafluorophenyl, using different aqueous eluant systems: acetonitrile-water mixtures;
